Valacyclovir HCl

General description
Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Valacyclovir HCl is the hydrochloride salt of L-valyl ester, a prodrug of the antiviral drug acyclovir. Its mode of action involves the inhibition of the viral DNA polymerase and the termination of the viral DNA chain.It is widely used against herpes zoster, herpes simplex and herpes B.
Valacyclovir is a prodrug of acyclovir. It is an L-valyl ester and works against herpes simplex virus type and varicella zoster virus.
Application
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
It was used as reference standard for the quantification of valayclovir and its metabolite, from human plasma using LC/ESI-MS method.
Valacyclovir HCl may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using spectrophotometric technique and reversed-phase high-performance liquid chromatography technique.
Analysis Note
These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
